Groupon offers Injustice: Gods Among Us Ultimate Edition for PlayStation 4, PlayStation 3, Xbox 360, or PlayStation Vita for $29.99 with free shipping. (Amazon has it for the PlayStation Vita for the same price.) That's tied with our mention from two weeks ago as the lowest total price we could now find for any of these platforms by at least $3. (It's also tied as the best price we've seen for a physical copy of this edition for any console.) Offer ends March 19 at 1 am ET.
